Add a target_override hook that takes priority over builtin targets.
Libc isn't used by alloc.
And std and panic_* use libc from crates.io now,
which isn't feature gated.
The Rust version number is currently embedded in bootstrap's source
code, which makes it hard to update it automatically or access it
outside of ./x.py (as you'd have to parse the source code).

This commit moves the version number to a standalone plaintext file,
which makes accessing or updating it trivial.

This is specifically disallowed by the RFC, but we never added a check
for it.

Let backends define custom targets

Add a target_override hook that takes priority over builtin targets.
Remove unused feature gates from library/ crates

Removes some unused feature gates from library crates. It's likely not a complete list as I only tested a subset for which it's more likely that it is unused.

Move the version number to a plaintext file

The Rust version number is currently embedded in bootstrap's source code, which makes it hard to update it automatically or access it outside of ./x.py (as you'd have to parse the source code).

This PR moves the version number to a standalone plaintext file, which makes accessing or updating it trivial.

…xamples, r=Dylan-DPC

Add missing examples on HashSet iter types
use matches!() macro for simple if let conditions
don't take `TyCtxt` by reference

small cleanup
transmute: use diagnostic item

closes rust-lang#66075, we now have no remaining uses of `match_def_path`  in the compiler while some uses still remain in `clippy`.
